Title: Improvements in savings clocks
IPC: G07F17/00
Filed: 1920-09-10
Abstract: 173,027. Wiingaard, A. G. P. Sept. 10, 1920. Addition to 115,657. C l o c k s combined with money - boxes.- The savings clock described in the parent Specification is provided with means for operation by folded paper money as well as by coins. A folded biil 26 inserted through a slot 24 in the clock casing rests on the lower end 29 of a bent plate 27 pivoted at 31, the end 29 having a finger-piece 30 projecting through a curved slot 25. The bill first acts on an oblique lug 23 on a lever 21 in contact with a projection 13 on the depending arm 5 of the three-armed lever 5, 6, 7, described in the parent Specification, thereby moving the arm 5 a little towards the left. Then, by depressing the finger-piece 30 against a spring 28, the plate 27 pushes the bill into a money chamber 33, the bill in its passage moving the arm 5 fully to the left and causing the arm 6 to release the stop 9 from the balance wheel 4 and the arm 7 to enter the notch 10 in the coin-shoot 1.

Title: Apparatus for generating sonic vibrations in liquids
IPC: B06B3/00
Filed: 1959-07-30
Abstract: 876,279. Piezo-electric devices. BENDIX CORPORATION. July 30, 1959 [Sept. 8, 1958], No. 26249/59. Class 40 (4). A transducer for generating sonic and ultrasonic vibrations in a tank of liquid comprises a hollow cylindrical element 25 of barium titanate in which the electrodes 29, 30 of two sets are arranged alternately. The two sets are used to generate electrical fields and mechanical vibrations in a longitudinal direction. Inner and outer cylindrical electrodes can be used. The transducer has an aluminium head 26 and a stainless-steel face plate 27. The tank bottom comprises a layer 14 of rubber between two thinner layers 15, 16 of metal. The head 26 is a press fit in an aperture in the rubber layer 14 but the face plate 27 overlies the layer 14 around the edge of the aperture and does not contact the edge of a larger aperture in the top layer 16. There is also a gap between the bottom layer 15 and the wall of the element 25. A massive ring 28 may be attached to the transducer. In a modification, Fig. 2, the head 34 is formed as an integral part of the ceramic element and the part 35 joining the head to the active section 33 is formed as a coupling with a cross-section as shown. The modification is suitable for use with a liquid at a temperature above 120‹ C. at which temperature barium titanate loses its electromechanical properties. The active section is divided into four segments by slots 37. Electrodes 38, 39 are arranged alternately as before. Each electrode may extend around its segment. Electrodes on adjacent segments are linked by connectors 40. In each of the embodiments shown, the length of the transducer is one or more half wavelengths. In Fig. 2, the overall length may be one half wavelength and the active portion 33 may be a quarter wavelength.

Title: Improvements in and relating to continuous flow liquid heating apparatus heated by liquid fuel
IPC: F24H1/16
Filed: 1932-09-21
Abstract: 385,916. Actuation of switches. JUNKERS & CO., GES., 35, Junkerstrasse, Dessau, Anhalt, Germany.-(Assignees of Junkers, H. ; 21, Kaiserplatz, Dessau, Anhalt, Germany.) Sept. 21, 1932, No. 26264. Convention date, Sept. 26, 1931. [Class 38 (v).] A switch actuated by a water tap sets in operation a rotary atomizer within a burner used in a continuous flow liquid heater. The tap 7 controls water supply through a pipe 5 with a constriction 20 to a pipe coil 3 attached to a wall 2. The pressure difference on the two sides 21, 22 of the constriction 20 when water flows, moves a diaphragm 24 and so closes a switch 27 controlling an electric motor 8 driving a rotary atomizer 10 and an air supply fan 15. When the tap is turned off, the switch reopens. Oil fuel from a bird fountain supply 13 flows to a cup 12 containing a cone 10 with a dependent cylinder 11 immersed in the oil and rotating on a shaft, 9 of the motor. Oil rising in the cylinder 11 is sprayed as a mist by the rotating cone 10 and is ignited by a pilot burner 17, to which access is given by a cap 18. A further switch actuated by water pressure may cut out the burner when there is no water in the heater.

Patent GB-845756-A (GB)
Title: Improvements in or relating to the production of self-supporting films
IPC: B29C48/08
Filed: 1956-08-31
Abstract: An apparatus for making self-supporting films comprises a rectangular hopper having a front wall 40 (Fig. 3) and a rear wall, both of which slope internally towards the centre of the hopper bottom as indicated at 42 and 44.  The longi <PICT:0845756/IV(a)/1> tudinally extending opening 47 in the bottom of the hopper is narrowed by means of elongated edge members 58 and 50 to form a slot and rotatably mounted above and parallel with the slot with its underside adjacent to the edges of the slot is a roll 68 driven anti-clockwise through an infinitely variable speed reduction gear by an electric motor.  The sloping surface 60 of the edge member 58 in coextensive with the sloping wall 42 and terminates in a sharp edge 62 which forms one edge of the slot and is spaced from the roll 68 by a gap 63 through which the viscous film-forming solution in the hopper is discharged. The opposed edge member 50 has an upwardly directed ridge of inverted V cross-section whose edge 54 is spaced a very short distance, e.g. 0,002 inch, from the roll 68 and functions as a stripping blade for removing all but a very thin film of the solution from the roll 68. The member 50 also has a downwardly directed ridge of V-shaped cross-section whose edge 52 serves as a doctor blade to level out the film of solution on the peripheral surface of the casting drum 16 which is slowly rotated in a clock-wise direction. The film F of solution stripped from the roll 68 by the blade 54 flows down the surface 53 of the member 50 on to the peripheral surface of the casting drum 16, leaving a thin inner layer of solution adhering to the peripheral surface of the roll 68 upon which it is carried back into the hopper and facilitates the pick-up of further solution from the body of solution in the hopper during the next revolution of the roll.  The hopper is supported by shoes attached to the side walls of the hopper and adapted to ride on the peripheral surface of the drum 16.  The front of hopper is also supported by means of a pair of adjustable pins 72 which screw into ears 43 projecting from the front wall of the hopper and are provided with knurled knobs 70 and engage soft metal slide buttons 12 mounted on metal leaf springs 11.  The hopper may be heated by means of electrical heating elements housed in two bores in the lower portions of the hopper walls, one of which bores is shown at 45.  In addition to providing films of uniform thickness, the rotating roll 68 causes air bubbles to be removed from the viscous film-forming solution before it passes through the gap 63.  Specification 642,902 is referred to.
